If you're one of those people who thinks the Boston Crab isn't painful, think again ... because last night an MMA fighter locked it onto his opponent and made the guy tap out.

A fighter named Jonno Mears defeated Aaron Jones at Full Contact Contender 19 in Bolton, England and he somehow did it by using a submission that's usually reserved for pro wrestling.

Chris Jericho -- who uses it as a finishing move -- tweeted about the victory and said, "Hahah see the #WallsOfJericho really works!"

Check out the impressive feat in the video below.
